Question

the angle of elevation from a ship to the top of a 35 m lighthouse on the shore measure 28 degrees. How far is the ship from shore

Answer 1

I'm not sure, but it should be around 65.825.

If you put 28 into tan(), you'll get about 0.5317

If you then divide 35 by that, you'll get about 65.826ish.

I'm relatively sure that's what it is.
